iOS KeychainItemWrapper not updating

I just found an interesting problem with my app. In the app I am saving the user's user name and password to the keychain.

keychainWrapper = [[KeychainItemWrapper alloc] initWithIdentifier:@"MyLoginPassword" accessGroup:nil];

[keychainWrapper setObject:usernameField.text forKey:(id)kSecAttrAccount];
[keychainWrapper setObject:passwordField.text forKey:(id)kSecValueData];

When this code is run in Debug it seems to work just fine. It updates each time and I can later retrieve the items from the keychain. When it is run in Distribution however the keychain never gets updated. I have verified that yes these lines of code are hit in both builds. I am using Xcode 4.2 with the iOS5 SDK and running the app on an iPad 2 with iOS5 installed.

When you include

keychainWrapper = [[KeychainItemWrapper alloc] initWithIdentifier:@"MyLoginPassword" accessGroup:nil];

[keychainWrapper setObject:usernameField.text forKey:(id)kSecAttrAccount];
[keychainWrapper setObject:passwordField.text forKey:(id)kSecValueData];

you also had to include

[keychainWrapper setObject:@"Myappstring" forKey: (id)kSecAttrService];

Or I get a "SIGABRT" error. (Myappstring) is a string defining your application.

Maybe I'm missing something, this should be done at least once.
